PASTRYQBAKING MACHINE.

To all whom it may concern:

Be it known that I, Crmn'nns STUP}AN, a subject of the King of Hungary, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Pastry-Baking Machines, of which the following is a specification.

My invention relates to pastry-baking machines of that class having mold members or dies in which pastry cones, cups, or other hollow articles are molded and baked.

The primary object of my invention is to provide a machine of that class in which provision is made for bringing the die members together by a rectilinear movement of at least one of said members, so that the batter will be forced equally 'in all directions from a center line, thereby assuring a and to otherwise improve on machines of this class now in use.

-My invention consists of the combination with a plurality of cores or male dies, of a plurality of female dies toward and into which' the male dies are movable in recti- Ilinear lines and which female dies are composed of sections relatively movable at right angles to the movement of said cores or male dies.

It also consists in the provision of novel means for separating the sections of the female dies; in the provision of a heating device in operative relation to said female dies and in a heating devicemovable with said cores or male dies.

It further consists in a plurality of male and female dies relatively movable in verti cal planes; in the provision of means for automatically cutting off the heat from the female dies when separated from the cores or male dies, and in thenovel features of Specification of Letters Patent.

construction and the arrangement and combination of partsto be hereinafter described also in sectional view the continuation of" the support used in connection with the ma-- chine. Fig. 6 is an enlarged vertical section through a portion of the male die memberand its supportedburner. Fig. 7 is a horizontal section taken on line y Fig; 1,

and Fig. 8 is an enlarged transverse section taken on line zz ,,'Fig. 3. 1

Referring now tov the drawings in detail, like characters of reference refer to like parts in the several figures.

The reference letter A indicates a frame which is preferably rectangular in formation and supported upon suitable legs a, so

as to hold the frame elevated. Arranged within said frame is one or more die mem- Patented Dec. 1, 1914.

bers B, there being three shown in the pa-rticular machine illustrated. These die members may be. termed the female die members since in them areformed concavities b of such formation as the finished product 1s to have. Each die member has two longitudinal series of such concavities and is formed of three sections, C, D, E. The in cavities; in other words, the female die member is separable centrally through the ever, that'the arrangement of the concavities may be departed from that herein shown. The female die members B are sup- F fastened into opposite ends of the frame and these rods serve as guides upon, whichv the two outer sections of each member are guided for movement toward and from their cooperating intermediate'section. Said intermediate sections are 'held against moveconcavities therein. It is apparent, howported on a pair of longitudinal guide-rods said intermediate sections.

said intermediate sect ons are held so as to ment on the guide-rods F by means of shafts G arranged at right angles to the guide-rods I and passing longitudinally through the intermediate sections, said shafts being 3' ournaled in the opposite side walls of the frame A, as at g.

Arranged at, opposite ends of each female die member are double levers H, which are fastened centrally to the shafts G and pivotally secured to opposite ends of each lever are links I, which are connected to studs '5 extending from the ends of the outer sections of each female die member. Secured to the shafts G are gear wheels J, which are preferably arranged outside of the frame A,

ment of the intermediate section of each fe male diev member on the guiderods F, bolts M are passed through the side Walls of the frame A. and threaded into opposite ends of By this means,

prevent lateral strain on the shafts G and thus assure freedom in action without tendency to bind.

Arranged beneath the female die members is'a' gas burner or other heating device N having jet-s n so located as to be positioned directly beneath the concavities in the fe male die members, a suitable fuel supplypipe 0 leading to the burner, as is common.

Rising from the frame Aare combined supports and guide rodsP, to the upper end of which is securedfasecond frame 72, and mounted on bearings on said frame is a shaft Q having secured thereon a pair of gear wheels and having also fastened. to i one of its ends an operating wheel 13 and a sheave r, for a purpose to appear hereinafter.

S represents a male die member which is guided for rrovement on the vertical guide rods or supports P. and comprises a plate 8 having openings T therein and male dies or cores t fastened to the underside of said plate, said male dies or cores are of a shape to correspond to the concavities in the female die members but are made a trifle smaller than said concavities and they are also made hollow with the opening in the plate s registering with the interior of said dies or cores. V These male die or cores are positionedcentrally with respectto the corn cavities of the female die members and when miaeaa 9 on the shaft Q, and supported on said die member is a burner or other heating device V having jets a directed downwardly into the hollow male dies or cores. The flames from the burners N and V play, respectively, against the under sides of the female die members directly beneath all the concavities therein and against the interior surfaces of the hollow male dies or cores. Connected to the'burner V is a supply-pipe W to which may be attached a hose so that the male die member can be raised ahd lowered without interfering with the supply. of the fuel.

. Wound around the sheave r is a cord or cable X which is directeddownwardlv for connection to one end of a baffle plate as. This baffle plate passes through a slot Y formed in one end wall of'the frame. A and receivessupport from rollers 1 fastened rotatably to tracks Eeiitending from the wall of the frame A having the slot Y therein to the opposite wall and being secured to both.

Said cord or cable X passes around a sheave z journaled ina bracket secured to the frame A.

Adjacent the frame A is a frame 10 from which rises an arm 11 having a pulley 12 .at

its upper end, and secured to the baffle plate m is a cord or cable 13, which .passes around a pulley 14 on frame 10 and also around the .pulley 12, thence downward from the latter, and to the end thereof is attached a weight 15'. On the frame 10 are placed a plurality of supportingrollers 16 on which the bafile plate a: rides when drawn outward from the frame A.

I The operation of the device is as follows :'lhe batter used for baking the cones or other hollow articles is poured into the concavities b in the required quantities, after. which the operator lowers the male die. member with its supported heating-device by too rotating the shaft Q, thus bringing the male dies or cores centrally into the concavities burner to come in direct contact with the female die members and as the burner U is at all times heating the interior of the male dies or cores, the batter is baked from the inside as well as the outside and thus results in a quick baking of the batter within the dies. 1

When the cones or other hollow articles are properly baked,-the operator takfifi hold of the operating wheel R and rotates the shaft Q to'elevate the male die member and cause I the cord or cable X to be wound upon the sheave'r, thus drawing up the weight 15 and causing the baffle plate to be moved into the frame A between the female die members and the heating device N, thereby preventing the heat from said heating device N coming in direct contact with said female die members. After the male die members are elevated and the baflie plate thus positioned, the operator depresses the operating lever against the action of the retractile spring Z, causing the gear wheels J to turn and with them the shafts G to which they are secured. 1 In this manner the double levers H are swung from their vertical position toward a horizontal position, whereupon the links I, pivotally secured thereto, act to separate the three sections of the female die members, so as to permit the ready removal of the baked cones or other hollow articles from the concavities in which they are formed. After removal of the finished articles from the female die members, theoperator may release the lever K, whereupon the retractile spring I, re-. 'turns said lever to normal posit on and causes the sections of each female-die memher to be brou ht together, ready for the reception of a urther supply of batter into the concavities thereof.

".It will be apparent from the foregoing that my invention may be embodied in various modified forms and that changes may be made in the construction of parts without departing from the spirit of my invention or sacrificing any of theradvantages thereof.
